The present disclosure relates to an electronic load apparatus. An embodiment of the present disclosure includes an electronic load apparatus including: a measurement resistor, a reference circuit, a transistor, and a feedback circuit. The measurement resistor includes a first contact, a second contact, a third contact, and a fourth contact. The first contact and the second contact are located at a first end of the measurement resistor. The third contact and the fourth contact are located at a second end of the measurement resistor. A reference power (or a reference voltage) electrically connects to the reference circuit. The reference circuit and the first contact of the measurement resistor are electrically connected. The transistor includes a drain, a gate, and a source. The reference circuit and the gate of the transistor are electrically connected. One of the source and the drain of the transistor electrically connects to the second contact of the measurement resistor. The other one of the drain and the source of the transistor electrically connects to an output terminal of a unit under test. The feedback circuit and the fourth contact of the measurement resistor are electrically connected. The feedback circuit and the reference circuit are electrically connected.

Electronic load apparatus

An electronic load apparatus is provided and adapted to allow an enhanced driving circuit to be disposed between a voltage-dividing circuit and power components to ensure the driving capability of the power components not coupled to a control circuit to thereby adjust a response voltage quickly, shorten a response time period and thus increase overall response speed, suppress transient voltage variation and thus preclude a signal delay otherwise arising from a load circuit, allow the power components series-connected in an electronic load apparatus to be driven quickly, reduce the risk of damaging the power components, and enhance the stability and reliability of the electronic load apparatus.
